Get Sales Owner Name

Hello,
I want to move a Note from Deal to Contact.
That works fine but I want to include sales owner name in the new note.
I get “creater_id” from the note I am transferring and I am assuming its the user ID of the note creator.
How can I get the Full name of the User?
I tried https://.myfreshworks.com/crm/sales/api/users/{{creatorID}}
